Hi,We have had so many requests about adding the download time and journal's URL to the article that is being downloaded.I'm not familiar with php coding so I've created a web service in C# which does the job.It receives the PDF address and returns the modified file.for example, this is the output (address, date and time of download are added to the left margin of each page):http://www.medinfotechs.com/pdf/watermark.asmx/watermark?input=http://www.ijnmr.mui.ac.ir/index.php/ijnmr/article/view/505/432This is just a test version and is not finished yet, but is functional.Can any one help me adding this web service to OJS?It could be added as a plugin which is accessed at the download time.Any help is appreciatedCheers,

Hi everybody,I managed to add the link of this webservice to pdf galley links in our journals' websites.If you like to use this service too, you must add the mentioned link in article.tpl and issue.tpl files.Cheers,

That's a really interesting bit of functionality! I don't know of any way to do this via PHP natively myself, and the only other (quick) solution I could think of would be to timestamp the download file's filename itself. Can you control how and what is stamped into the PDF itself fairly easily?
